Polymarket Perps Calculator

Reference implementation of the platform's perps mechanics, from the official documentation (October 2026).

Notional ($)

Max leverage

Mean premium (decimal, e.g. 0.003)

Funding scale (1.0 crypto / 0.5 other)

Formulas: MMR = 0.5/MaxLeverage; F_8h = scale × (mean_P + clamp(0.0001 − mean_P, ±0.0005)); FR_hour = clamp(F_8h/8, ±0.04); withdrawal floor = max(CollateralReserved, 10% × TotalPositionValue). Educational tool, not financial advice. Source: docs.polymarket.com/perps.
